At last they told how in the near-by plain of Wandlesbury there was a haunted mound. There in old days the Vandals, who laid waste the land and slaughtered Christians, had pitched their camp and built about it a great rampart.
And it was further related that in the hush of the night, if any one crossed the plain, ascended the mound, and called out in a loud voice, "Let my adversary appear!" there immediately started up from the ruined ramparts a huge, ghostly figure, armed and mounted for battle. This phantom then attacked the knight who had cried out and speedily overcame him.
